Anecdotally, I have the opposite suspicion. I think the 1% figure is an underrepresentation and may only account for people who have sought clinical support for their problem. For instance, one time, in one of my grad school seminars, there were only 7 people in the classroom—myself, four other classmates in my cohort, plus the professor and a guest speaker. I stutter and I stuttered throughout the class discussion, *another* of my grad school classmates was a stutterer and stuttered throughout his participation in the class, *plus* the guest speaker turned out to be a stutterer and stuttered maybe worse than the both of us did. So, what are the odds, if only 1% of the population stutters, of us three all horribly stuttering at one another in a classroom of 7?
